To all whom-it may concern: Y Be it known that I, DAVIS L. MABRY, a citizen ofthe United States, residing at Idabel, in the county of McCurtain and State of Oklahoma, have invented a new and useful Improvement in Aeromobiles, of

-- which the'following is a specification.

This invention relates to an aeromobile, whichis designed to car y a large number of passengers and which is provided in addition to the usual lifting and steering planes with an attachment adapted to operate after the manner of a parachute, thereby increasing the safety of the device.

The invention also consists of the novel features of construction hereinafter described, pointed out 'in'the claims and shown in the accompanying drawings, in which,

Figure '1 is aplan view of the device, certain parts being omitted. Fig; 2 is aside elevation, seats. being omitted. 'Fig. 3 is an enlarged, central, vertical section. Fig. 4-is a horizontal section through the body porver tion of the device, the passenger seats being omitted. Fig. 5 is a detail sectional view illustrating a frictional brake band.

In constructing the device,,I employ two parallel skeleton frames 1 and 2, which are substantially triangular in outline and arranged one above the other. Adjacent their corners. these frames are provided with suitable vertical walls1or braces 3.} The body inclosed by the frames 1 and 2and the vertical braces 3 forms atriangular box-like device which forms the central body portion of the aeroplane and carries the engine, most of the operating machinery, and provides seating room-for the operator and passengers. The lower frame 1, forms the floor.

provided with a small gear 10, which meshes with a large gear 11, carried by a shaft 12, of a suitable motor 13.

- From the corners of the body portion ex tend upper and lower parallel arms 14, and

15, said arms being respectively-extensions.

of the frames 1 and 2. In the outer por- I tionsof these arms are rotatably mounted vertical shafts -16, said shafts being of less height than the central shaft 6. -The shafts 16, are all driven by horizontally arranged shafts 17, which at their inner ends are provided with beveled gears 18, which mesh with "a beveled gear 19, carried by the shaft 6.

.,It will be obvious therefore that all four of the shafts heretofore mentioned will be rotated in unison from the motor 13, each of the' shafts carries a pair of adjustable Patented Dec. 10, 1912. y

and normally opposite inclined planes 20,

said planes being rectangular in outline and being mounted upon horizontally arranged arms 21. These planes are held 'in their adjusted positions by means of suitable cords or wires 22 connected to the planes and. to

lower cross arms. 23 also carried by' said vertical shafts.

"It wi'll be obvious that as the shafts are rotated the inclined planes will rotate with them. All of the shafts. and planes are substantially alike in construction but the shaft at the front corner is fitted with a suitable horizontally swinging bracket 24', carried by said shaft upon suitable ball bearings and this shaft carries also a bevel gear 25, which meshes with a bevel gear 26, carried by the inner end of a horizontally arranged and forwardly extending shaft- 27, which is mounted in suitable bearin sformed in the bracket 24. .This shaft like the vertical shafts is also provided with a'cross arm 28,

upon whichare mounted obliquely and op- I positely disposed rectangular planes 29,

held in. position by wires or cords 30,se-

cured to 'across arm 31 These last mentioned planes form the steering planes and the bracket 24 .isadapted to be swung in a -hor1zontal plane by means of a cable 32,

which winds upon.a suitable drum 33, which drum forms 'a steering wheel operating similar to those employed in the handling of ruddersgthe drum-or wheel being manually operated. In' order to slacken speed of ro-- tation of the shafts a friction brake 34 is provided for the central shaft 6, said brake being operatedfthrough the medium of. a M

pivoted brake rod 35, link' 36 and lever 37 Hmged frames 41, are carried by the sides of the body portion and the said frames are covered with cloth or canvas as shown at 42,

which serye as both awnings, as planes, when they are 1n raised position and as parts of the parachute device. This latter consists the collar 38 uses upon the shaft 6, the

hinged frames will-be opened thus bringing the awnin s or covering'37 into use for th purpose 0 checkingthe descent. It will ,of course be understood that suitv --able seats may be provided for passengers prising a box like structure,a plurality of and these may be arranged in any desired manner.

What I claim isi 1. A device of the kind described comvertical shafts one of said shafts bein ar ranged centrally with respect to the sai box like structure, means for rotating said shafts, inclined adjustable lanes carried by said shafts and rotating with them, a collar loosely carried by the central, shaft, a parachute carried thereby, hinged frames-cartried by. the said box structure, and ,means connectingsaid frames with the edges of the parachute, whereby said frames are elevated as the parachute opens.

- 2. The combination with a device of the kind described having a central vertical shaft, of a collar loosely mounted on said shaft, a parachute carried by said collar,

hinged frames carried by the body portion of the device, and cords connecting said frames with the free edges of the parachute, asv and for the purpose set forth.
